G-eometridae of the Argentine Republic. 280 
possible it is only a very extreme aberration of M. 
apriearia. 
146. Melinoides albarita (Dognin). 
Iteterolocha albarita, Dognin, Ann. Soc. Ent. Belg., xxxvii, 
158 (1893). 
Tucuman, in coll. Dognin. 
Described from Loja. I have seen a large number from 
Bogotd, Colombia. 
147. Numia deceptrix (Warren). 
Nuiiiia deceptrix, Warren, Nov. Zool., xii, 69 (1905). 
Tucuman, in coll. Rothschild (type) et Bastelberger. 
148. Perusia citrinata (Snellen). 
Perusia citrinata, Snellen, Tijd. Ent., xvii, 25, tab. ii, 1 
(1874). 
Salta, in coll. Dognin. 
Snellen’s type was from Bogotd. I believe the species 
(or form) is widely distributed. 
149. Microxydia orsitaria (Guenee). 
Stegania{T) orsitaria, Guenee, Spec. Gen. des Lep., x, 49 
(1858). 
? Rumia defixata. Walker, List Lep. Ins., xxvi, 1499 
(1862). 
? Goi'ycia sulphurata, Maassen, Stlibel’s Reisen, Lep. 161, 
tab. viii, 18 (1890). 
? Microxydia rufifinibriata, Warren, Nov. Zool., xi, 574 
(1904). 
Tucuman, in coll. Dognin et coll. Bastelberger. 
Widely distributed throughout a great part of the 
Neotropical Region, though I am not aware of its occurrence 
further south than Tucuman and S.E. Brazil. 
“Varies excessively,” as Guenee gathered even from the 
three specimens known to him. It is probable that the 
names cited in the synonymy above should be sunk to it, 
and not unlikely some of the others which have been 
brought forward as new species of Microxydia.
